The new line of power supply offers you all the safety, performance and control of a completely independent channel technology at the cost effective price of a distributor! You will never have to compromise!

A7030 family house 48, 36, 24 or 12 independent high voltage channels available with either positive, negative polarity, compatible with the CAEN Universal Multichannel Power Supply Systems (SY1527, SY2527, SY3527, SY4527, SY5527).

The channels share a Common Floating Return, which allows on-detector grounding, reducing the noise level.

The output voltage range is 0 ÷ 3 kV, with 5 mV monitor resolution. The maximum output current is 1 mA (1.5 W max. output power), with 2 nA monitor resolution.

A7030 are supplied in different versions equipped with SHV or with Radiall Multipin connector.

Two A7030 versions are designed for higher altitudes (Operating Altitude: 0÷5000 m)::
pnt A7030Y - 48 channel Radial multipin connector
pnt A7030YS - 24 channel SHV connectors

Independently programmable for each channel:
pnt Output voltage:
pnt Current limit (Iset):
pnt HV Ramp up/down:
pnt TRIP parameter
0 ÷ 3 kV
0 ÷ 1 mA
1 ÷ 500 V/sec
step: 50 mV
step: 20 nA
step: 1 V/sec

Safety features
arrow Channels can be enabled or disabled through the Global Interlock logic.
arrow Overvoltage and Undervoltage warning when the output voltage differs from the programmed value.
arrow Hardware VMAX and IMAX: maximum output voltage and maximum current value can be fixed, via front panel potentiometer, at the same common value for all the board channels. IMAX and VMAX values can be read out via software.
arrow Overcurrent detection: when a channel attempts to exceed the programmed current limit (Iset), it signaled to be in "overcurrent" and enter in a TRIP status: the channel is switched off after a programmable TRIP time. The output current is permitted to exceed Iset value, the channel behaves like a current generator only if the IMAX current value is reached.
arrow Safety Board Interlock: this protection disables the HV generation when the HV outputs are not connected to their loads (only for Multipin Connector versions).
Universal Multichannel System - Mainframes
Modularity, Compatibility, Connectivity, Usability and Solidity are the keywords of the system design. The Mainframes have been specifically designed to power all detector technologies found in modern Physics Experiments, such as photomultipliers, wire chambers, streamers tubes, silicon detectors and others.

The systems are modular, flexible and match not only the requirements of major experiments with large number of channels but also the practical needs of test laboratories, where simple manual operations on a limited number of channels are often desired.
